分布的混合 meaning in Chinese

mixture of distribution

One is a sparre andersen risk model in which the claim inter - arrival distribution is a mixture of an exponential distribution and an erlang ( n ) distribution
首先主要讨论了索赔时间间隔的分布为指数分布和erlang ( n )分布的混合的sparreandersen风险模型。
Our main contributions are summarized as what follows : ? theoretical : suppose data were sampled from a mixture of m d - variate t - distributions ; and each mixing component satisfies an isotropic factor analysis model ( see ? . 2 . 1 )
具体说来，我们的主要工作包含以下内容：理论方面：假设数据来自m个d元t分布的混合；而每个混合成分均满足迷向( iso - tropic )因子分析模型见3
The integrands in the dispersion equation are not integrable in general , so we used the asymptotic expansion solution to analyze the behavior of the dispersion relation at the singularity and mapped the dispersion relation curves approximately the system composed of collisionless particles which obey maxwellian distribution or all kinds of degenerate distribution , even in their mixture system , their dispersion relation are analogous
一般来说，色散方程中的被积函数都是难以求积的，本文是用函数逼近法分析色散方程在奇点处的行为，并大致划出色散关系曲线。由无碰撞粒子组成的系统，不管初始分布是maxwell分布还是各种简并分布，甚至是这些分布的混合体，色散关系都是相似的。
